An experiment was conducted to study the effect that varying the amount of glucosinolates and free oxazolidinethione (OZT) in a laying diet containing a constant amount of sinapine had on the trimethylamine (TMA) content of eggs and the incidence of fishy eggs from brown-shelled egg layers. Duplicate groups of 10 Rhode Island Red laying hens which had been found to lay fishy eggs when fed a diet containing 10% rapeseed meal (RSM) were fed each of the four experimental diets. The diets consisted of a wheat-soybean-meal-type control diet and three diets to which aqueous extracts of RSM produced from high, medium and low glucosinolate cultivars (Oro, Span and Tower) were added. The extracts were included in the diet at levels of 3.42, 4.4 and 5.0%, respectively, to provide a sinapine content of 0.17%, a level equivalent to that which would result from the inclusion of 10% RSM in the diet. The results showed that the TMA content of eggs produced by the layers fed the diet containing Tower aqueous extract was significantly higher than that of eggs produced by birds fed the diets containing Oro or Span aqueous extracts (P < 0.05). Since the level of glucosinolates in the diets containing Oro and Span aqueous extracts were about seven times that in the diet containing the Tower aqueous extract, it may be concluded that intact glucosinolates do not affect the amount of TMA in eggs from brown-shelled egg layers fed a diet containing a constant amount of sinapine. On the other hand, free OZT in the diet increased the TMA content of the eggs and the incidence of fishy eggs produced by brown-shelled egg layers.

The effects of varying amounts of glucosinolate and free oxazolidinethione (OZT) in laying diets containing a constant amount of sinapine on thyroid size, hepatic trimethylamine (TMA) oxidase activity, and TMA levels in plasma and egg contents were studied. The diets fed contained aqueous extracts of RSM produced from high, medium and low glucosinolate cultivars (Oro, Span and Tower) which were included in amounts that provided the same level of sinapine in each diet. Thyroid size, plasma TMA levels and liver TMA oxidase activity were determined and eggs from individual birds in each treatment were analyzed for TMA content. The presence of progoitrin and free OZT in a laying diet significantly increased (P < 0.05) thyroid size and severely depressed hepatic TMA oxidase activity of the birds as compared to those fed a control diet. The degree of thyroid enlargement was largest for birds fed the Oro extract and was least for birds fed the Tower extract. The decrease in hepatic TMA oxidase activity, however, was greatest for layers fed the Tower extract and least for those fed the Oro extract. The decrease in TMA oxidase activity led to elevated plasma TMA levels and increased TMA content of eggs of brown-egg layers.

Two experiments were conducted to study the effects of supplementing broiler rations with a multiple cellulolytic enzymes system (Driselase) on the performance of chicks raised to 4 wk of age (exp. 1) and to 8 wk of age (exp. 2). Four broiler rations unsupplemented or supplemented with 0.03% Driselase were used in the study. One of the rations was based on soybean meal and wheat while the other three contained 20% rapeseed meal (produced from Regent, Candle and Turret cultivars of rapeseed) as a partial replacement for soybean meal. The results obtained in both experiments indicated a lack of response in body weight and feed conversion of the chicks to Driselase supplementation. In both experiments, the chicks receiving the rations containing rapeseed meal showed varying degrees of thyroid enlargement depending on the cultivar of rapeseed from which the meal was produced, with Turret meal causing the greatest increase in thyroid size.

Two experiments were conducted to study the effects of supplementing a laying ration containing rapeseed meal (RSM) with antibiotic drugs on the fishy odor and trimethylamine (TMA) content in eggs laid by brown-egg layers. Brown-egg layers (Rhode Island Red) which had been previously found to lay eggs with a fishy odor when fed a ration containing 10% RSM were used in these studies. In exp. 1, a basal laying ration containing 10% RSM was fed to 16 groups of brown-egg layers (12 birds per group) for a pretreatment period of 4 wk. Quadruplicate groups of these birds were then allotted to each of four treatments for a period of 4 wk. These were the basal ration without supplementation with antibiotic, and the basal ration supplemented with either aureomycin (220 g/1000 kg), penicillin (55 g/1000 kg) or with sulfamethazine in the drinking water (1000 g/1000 kg). Eggs produced by birds during the last week of the pretreatment and treatment periods were scored organoleptically for fishy odor and pooled egg samples from each group were analyzed quantitatively for TMA. The results showed that neither fishy odor score nor TMA levels in the eggs produced were affected by the addition of aureomycin or penicillin to the diet or by the inclusion of sulfamethazine in the drinking water. In exp. 2, 10 groups of brown-egg layers (five birds per group) were fed the same RSM-containing basal laying ration for 4 wk. Following the pretreatment period, duplicate groups of the birds were assigned to each of five rations prepared by supplementing the RSM-containing ration with penicillin at levels of 0, 27.5, 55, 82.5 and 110 g per 1000 kg. Eggs produced by the birds during the last week of the pretreatment and treatment periods were evaluated organoleptically for fishy odor and pooled egg samples from individual birds were analyzed for TMA quantitatively. Results obtained indicated that supplementing the RSM-containing laying ration with penicillin had no significant effect on the TMA content of the eggs produced.

Five swine experiments were conducted to evaluate rapeseed meal (RSM) of low glucosinolate content (Brassica napus L. cv. Bronowski). Two experiments involved 0, 25, 50, 75 and 100% substitution of either Bronowski meal or regular (B. campestris) meal for soybean meal or fishmeal used in the control diet. One experiment compared ad libitum-fed and partially restricted pigs. Another experiment involved digestibility studies, and the final one involved methionine and lysine supplementation. As the dietary levels of either Bronowski or regular RSM increased in the ration, protein digestion coefficients decreased from 79 and 80% to 76 and 78%, respectively, and energy coefficients decreased from 82% to 79 and 78%, respectively. The protein and energy digestibility coefficients for Bronowski RSM were estimated to be 68 and 59%; for regular RSM, 65 and 54%. With barley–wheat–RSM diets, pigs responded to 0.1% methionine, but not to lysine (P > 0.05). Pigs fed ad libitum consumed more Bronowski than regular RSM diet and performed as well as pigs fed soybean meal diets.

Six hundred and seventy-two 1-day-old male broiler chicks of two strains were used to assess the effects of diet and color of diet on feed consumption. Isocaloric isonitrogenous diets that contained soybean meal (control), rapeseed meal, or ground rapeseed were fed in either colored or noncolored form. During the starter period the birds were given a choice of two diets in various combinations whereas during the grower period no choice was available. In the starter period there were no significant effects of color or diet combinations on total feed consumption. Coloring one diet of a pair, however, tended to increase the difference in consumption between the two by reducing the intake of the colored diet. The one exception to this was the diet pair containing ground rapeseed, which was not affected when one diet was colored. The control diet was preferred, followed by the diets containing rapeseed meal and ground rapeseed, respectively, when a choice was available. When no choice of diet was available in the grower period the only significant effect of color was to increase consumption of the ground rapeseed-containing diet. Weight gain in both periods was highest on the control diet followed by the diets containing rapeseed meal and ground rapeseed, respectively.

Abstract The present study aimed to investigate the influence of supplementing beetroot (Beta vulgaris rubra) powder and its aqueous extract on the productive performance of growing geese. A total of 180 one-day-old goslings chicks of Chinese white geese were randomly distributed among five treatment groups containing three replicates of 12 birds each. Five experimental diets were formulated as follows: Control diet without supplementation (T1). In the second and third treatments, the beetroot extract was supplemented at 15, and 30 (ml/l) in drinking water; 15, and 30 (g/kg) beetroot powder (T4, T5) in basal diet respectively. Results indicated significant (p≤0.05) improvement in average body weight and weight gain from the 2nd to 12th week and total weight gain in treatment T2 and T4, which achieved the highest values compared to the control. As for feed intake, the T3 in the 6th week, T1 in the 8th week, and T2 in the 10th week were consumed a greater amount of feed compared to the other treatments, while no significant differences appeared in the 2, 4, and 12 weeks of age and in the cumulative period. No significant differences in the feed conversion ratio at age 2, 10, and 12 weeks, while the T5 in the 4th week, T2 in the 6th week, and the T4 in the 8th week, and the cumulative period showed the better feed conversion ratio compared to the other treatments. In conclusion, the supplementation of beetroot extract at 15, 30 (ml/l) or beetroot powder at 15, 30 (g/kg) improved the productive performance of growing geese.

Fishy Odor

Triplicate groups of four Rhode Island Red layers which had been previously found to lay fishy eggs when fed a ration containing 10% of rapeseed meal (RSM) were fed a laying ration, devoid of RSM, to which 0, 0.5, 1.0, 2.0 or 4.0 g of sinapine (as bisulfate) per kilogram of ration was added. Eggs produced were analyzed for trimethylamine and scored organoleptically for fishyness. Inclusion of more than 1 g of sinapine per kilogram of laying ration caused the birds to lay eggs with a fishy odor. The findings suggest that when RSM is included in the ration of such birds, the level of usage should be such that the ration will contain not more than 0.1% sinapine.

Diets containing 10 and 20% of either prepress-solvent commercial rapeseed meal or thioglucoside-free Bronowski rapeseed meal were fed to Large White turkeys from 6 days of age to market at 144 days. Twenty percent commercial rapeseed meal depressed gains in comparison with an isocaloric and isonitrogenous soybean meal control diet. The performance of turkeys fed Bronowski rapeseed meal was essentially equal to that of birds fed the control diet. Diets containing 10% commercial rapeseed meal and 10 or 20% Bronowski meal were utilized more efficiently from 55 to 111 days than from 6 to 55 days of age when compared with the control diet.

Body weights and feed-to-gain ratios of chicks fed diets that contained Tower rapeseed meal or soybean meal with conventional (13.5%) or high-protein (21.0%) wheats with and without supplemental lysine were compared. High-protein wheat-rapeseed meal diets required lysine supplementation for optimal gain, whereas conventional protein wheat-rapeseed meal diets did not. However, with equal energy in the diets, the rapeseed meal diets did not support as low a feed-to-gain ratio as the soybean meal diets.

In two experiments, 113 pigs were fed diets containing up to 25.3% low-glucosinolate, low-erucic acid rapeseed meal (cv. Tower = 00-RSM) or 31.3% commercially available rapeseed meal (C-RSM) as partial or complete replacements for soybean meal (SBM). The diets, formulated to be isonitrogenous and isocaloric, were fed ad libitum to the pigs from 4 to 10 wk of age. Serum triiodothyronine uptake (T-3 uptake) was greater (P < 0.05) in pigs fed the SBM diet compared with the other diets. In experiment 1, tetraiodothyronine (T-4) levels of 10-wk-old pigs fed the SBM diet were greater (P < 0.05) than pigs fed C-RSM or C-RSM + SBM diets. The free thyroxine index (T-3 uptake/100 × T-4) was lowest (P < 0.05) for pigs fed the C-RSM diet. In experiment 2, serum T-4 levels of pigs fed the SBM and 00-RSM + SBM diets were higher (P < 0.05) than for those of pigs fed other diets. Serum cholesterol levels of pigs fed the 00-RSM, C-RSM and C-RSM + SBM diets were higher (P < 0.05) than was found with the SBM or 00-RSM + SBM diets. Thyroid weight was greater (P < 0.05) in pigs fed the C-RSM or C-RSM + SBM diets. The height of epithelial cells was greater (P < 0.05) for pigs fed the 00-RSM and C-RSM diets and weight of epithelium of all pigs fed RSM indicated epithelial hypertrophy compared with those fed the SBM diet. The results suggested that thyroid function of pigs fed high levels of 00-RSM might be impaired compared with those fed SBM as the sole supplementary protein source in cereal-based diets, but less severely than with pigs fed C-RSM.
